Сравнительная агротехнологическая оценка возделывания яровой пшеницы в южной лесостепи Западной Сибири

Abstract. Long-term (more than 20 years) studies were carried out on meadow – chernozem soil in the southern forest-steppe zone of Western Siberia. In a stationary grain-steam crop rotation (steam-wheat-wheat-wheat-barley), a comparative assessment of fertility, the state of agrophytocenosis, yield and quality of spring wheat grain, depending on the placement of the crop in the crop rotation, the tillage system, and complex chemicalization was carried out. The purpose of the research is to establish the influence and effectiveness of multi-level agricultural technologies of spring wheat on the elements of soil fertility, the state of agrophytocenosis, productivity and technological properties of grain in the southern forest-steppe of Western Siberia. Research methods. In the southern forest-steppe agricultural landscapes, the effectiveness of multi-level agricultural technologies of spring wheat cultivation has been established, with an increase in yield from 1.51 to 3.24 t/ha (2.1 times) and a decrease in technological parameters of grain. For the first time, the share contribution of chemicalization components in increasing the productivity of spring wheat cultivated by steam and in the grain-steam crop rotation has been established. Two-factor experience: factor A – tillage system (dump-plowing on the head of 20–22 cm, annually; combined-plowing in the fallow field and under the third wheat after steam for 20–22 cm and flat-cut on the head of 10–12 for the second wheat after steam barley; flat-cut on the head of 10–12 cm for all crops annually; minimal – in the fallow field cultivation on the 8–10 cm. in other fields without autumn treatment); factor B – means of intensification (control – without chemicals, the option of complex application of chemicals included the combined use of fertilizers (N24 P36 per 1 ha of arable land), recommended herbicides, fungicides and retardants). Results. It was found that intensive agrotechnology with the use of fertilizers and plant protection products makes the main contribution to increasing the yield and technological parameters of grain – 30–35 %, precursors – up to 20–25 %, weather conditions of the growing season – 18–20 %, the system of tillage in crop rotation – 10–12 %. The complex application of chemicals contributes to an increase in crop biomass to 2080 g/m2 (by 49 %), reduces water consumption to 73 mm per 1 t\ of grain (2.7 times), optimizes the nutrient regime of the soil and the phytosanitary state of agrophytocenosis, which ultimately increases yields from 1.51 to 3.27 t/ha while improving the technological properties of grain gluten content up to 26.4 – 29.4 %. Long-term rational use of chemicals does not lead to the accumulation of ecotoxicants in soil and grain. The scientific novelty was revealed for the conditions of Western Siberia with the long-term rational use of chemicals, the accumulation of ecotoxicants in the soil and grain was not observed.

Influence of soil fertility on the yield and grain quality of spring wheat in the conditions of Central Siberia

The article presents the results of studies on the effect of mineral fertilizers on the yield and quality of spring wheat grain in the conditions of the Krasnoyarsk forest-steppe. The studies were carried out in 2022 at the Minino station of the KrasNIISKh in the soil and climatic conditions of the Krasnoyarsk forest-steppe. The soil of the experimental plot is represented by leached chernozem. The results of the research showed that the maximum yield of the studied grain crops was noted when applying a complex mineral fertilizer (azofoska) at a dose of 60 kg. a.i./ha - 2.85 t/ha (increase to control 0.96 t/ha).

REALISATION OF PRODUCTIVITY POTENTIAL AND GRAIN QUALITY BY VARIETIES OF SPRING WHEAT OF DIFFERENT MATURITY GROUPS

In the Middle Trans-Urals, on less fertile derno-medium-podzolic loamy soils with limited growing seasons, a comparative trial of spring wheat varieties from three maturity groups was conducted over four years. It was established that early-maturing, mid-early, and mid-season spring wheat varieties can produce good yields, grain, and seed quality. The realisation of the genetic potential of productivity and grain quality of types is primarily influenced by abiotic conditions, the unfavourable course of which is not always correct with technological practices. In terms of grain yield over three years, among mid-early varieties, the Kalinka variety stood out, and among mid-season varieties, the Chernozemnyural'skaya 2 variety, with results of 243 and 266 g/m2, or 2.43 and 2.66 t/ha, respectively. Under favourable growth and development conditions, grain yields of early, mid-early, and mid-season varieties exceed 5 t/ha. Regional conditions allow grain protein content to generally exceed 23.0%, meeting the requirements of classes I–III, and gluten quality meeting the needs of groups I–II. The quality of spring wheat grain is determined to a greater extent by the prevailing abiotic conditions rather than the genetic characteristics of the variety. The requirements for forming spring wheat grain do not promote the formation of heavy grains; the 1000-seed weight usually amounts to around 30 g. Grain yields produced by early, mid-early, and mid-season group varieties are typically characterised by high laboratory germination values (over 92 %).

Yields and Quality of Spring Wheat Grain in Intercropping System with Different Legume Species

Abstract Intercropping is a technique in which two or more crops are grown together that is reported to be soil and water friendly. Field trials were conducted at three different localities in the Czech Republic. Spring wheat was grown together with different legumes (Egyptian clover, crimson clover, red clover, white clover, common pea, dun pea, common vetch, bird’s-foot-trefoil, common kidney vetch, and fenugreek) in an organic cropping system. Two basic systems were compared mixture and row-by-row cropping. The yield of grain was lower on average in row-by-row cropping than in the mixture. Lower yields were found in Prague (PR) compared to Uhříněves (UH) and Zvíkov (ZV). The mixture system seemed to be more effective in grain production than cultivation in separate rows (PR 2.14 t/ha, UH 4.71 t/ha, ZV 3.00 t/ha) in terms of spring wheat grain yield in comparison with the mixture system (PR 2.45 t/ha, UH 5.44 t/ha, ZV 3.14 t/ha). Quality parameters such as crude protein, wet gluten, gluten index, Zeleny test of wheat grown with legumes were compared to the control. The mean quality parameters of both systems were the following: test weight 75.75%, crude protein 13.9%, wet gluten 31.5%, Zeleny test 56.2 mL, falling number 266.4 s. The combinations of spring wheat with Egyptian clover, white clover, common vetch, common kidney vetch, and bird’s-foot-trefoil are recommended as the most promising according to the results obtained across all sites and considering all parameters.

Grain quality of spring wheat (<i>Triticum aestivum</i> L.) cultivars developed in Western Siberia under the conditions of Northern Kazakhstan

Background. Environmental testing is the first stage of wheat breeding, the purpose of which is to identify wheat samples suitable for local environments and capable of forming a fairly stable yield and high-quality grain. The proposed study presents the test results for spring bread wheat cultivars of Russian breeding grown in arid environments of Northern Kazakhstan in order to preserve their yield and baking qualities.Materials and methods. The material of the study included 15 spring bread wheat cultivars. Protein and gluten content and the quality of gluten were determined using an infrared analyzer; the physical properties of the test were assessed using a Chopin alveograph and Brabender farinograph.Results. As a result of biochemical assessment, increased protein and gluten content and grain weight were observed in cvs. ‘Tyumenskaya 30’, ‘Aviada’, ‘Lutescens 585’, ‘Serebrina’, and ‘Tyumenets 2’. Dough deformation energy (W) characteristic of high-quality wheat and the balance in the P/L ratio (elasticity/elongation) were shown by cvs. ‘Tyumenskaya 33’ (290 a.u.; 1.15 P/L), ‘SKENT-3’ (307 a.u.; 0.89 P/L), and ‘Lutescens 585’ (374 a.u., 1.10 P/L). In laboratory baking, the volume of bread ranged from 620 ml (‘Tyumenskaya 27’) to 768 ml (‘Tyumenskaya 29’) with an average value of 707 ml. A baking quality analysis of the cultivars grown in the Northern Trans-Urals and Northern Kazakhstan demonstrated that the conditions in Northern Kazakhstan were more favorable for obtaining bread with an increased volume. On the basis of environmental tests and an assessment of a set of biochemical and technological indicators, cvs. ‘SKENT-3’ and ‘Tyumenskaya 29’ were selected. It makes sense to continue studying wheat cultivars that can be sources and donors of high-quality grain for the development of cultivars for the arid steppe of Northern Kazakhstan.

Influence of weather conditions on the yield and quality of spring wheat grain in the forest-steppe of the Middle Volga region

The purpose of the research is to evaluate the influence of weather factors in 2016-2021 on the yield and quality of grain of 18 varieties and 28 lines of spring soft wheat of competitive variety trial in the conditions of forest-steppe of the Middle Volga (Penza region). To characterize the meteorological conditions, the average daily air temperatures, precipitation and hydrothermal coefficient (HTC) were taken. In the analysis of grain quality, the content of protein and gluten in the grain, as well as flour strength, quality indexes of the variety and farinograms of the dough were used. The result of the research stated the negative correlation between the yield and air temperature in June r = -0.518±0.128 («booting» phase), in August it was slightly weaker r = -0.342±0.141. Correlations of the yield with precipitation and HTC were positive. The average significant correlation of the yield was formed with precipitation and HTC in June: r = 0.509±0.130 and r = 0.552±0.126, respectively. A significant negative correlation was found between the yield and protein and gluten content in the grain: r = -0.758±0.098 and r = -0.782±0.094. The content of protein and gluten in the grain were almost functionally dependent on each other – r = 0.945±0.055. A high positive correlation has developed between the content of protein and gluten in the grain with the average daily air temperature in the second half of the growing season in July r = 0.845±0.081 and 0.902±0.065, in August: r = 0.858±0.080 and 0.898±0.075, respectively. Positive weak correlation was found between the yield and flour strength, variety quality indices and dough farinograms (r = 0.354±0.148, 0.402±0.138 and 0.423±0,136), respectively. Precipitation and a high rate of HTC in the second half of the growing season reduced the quality indices of the variety and farinograms of the dough, the strength of the flour. This dependence was characterized by a weak negative relationship: from r = -0.310±0.144 to r = -0.458±0.134. Thus, the formation of yield and quality indicators of grain of spring soft wheat is influenced by the temperature regime and the amount of precipitation in all phases of growth and development of plants.

This article presents the results of studying the sowing dates in 2016-2020. Spring wheat was sown in three terms: the first – optimally early – after pre-sowing cultivation (control), the second – 6 days after the first and the third – 12 days after the first sowing period. Studies on the depth of seeding were conducted in 2018-2020. Field experiments provided for testing the depth of seeding at 4, 6 and 8 cm. The influence of the nutrition background on the yield and grain quality of spring wheat was studied in 2018-2020 with the introduction of fertilizers based on 3 tons of grain per hectare. The studies were conducted with the zoned variety Yoldyz. The experiments were laid in the agrobiotechnopark of the Kazan State Agrarian University on gray forest soil with a humus content of 3.1-3.4% (according to Tyurin), P2O5 – 240-260 mg and K2O – 132-180 mg per 1000 g of soil. The early sowing period in all the years of research provided a higher yield of spring wheat. With a 6-day delay in sowing, the yield decreased by an average of 0.32 tons per ha over 5 years. Planting seeds deeper than 4 cm did not provide an increase in yield, and in all years of research led to a decrease. The use of fertilizers on average for three years increased the yield of spring wheat by 0.8 t/ ha. The protein content in grain on a fertilized background was 2.6% higher, and the mass fraction of gluten was 4.1% higher.

This article presents research materials on the effect of mineral fertilizers on the yield and quality of spring wheat grain. It was found that in the conditions of the Pre-Kama region of the Republic of Tatarstan on gray–forest soils (on average for two years – 2019-2020), the dose of mineral fertilizers NPK is the most effective. Agrometeorological conditions during the years of research were favorable, GTK – 1,36 and 1,13. The object of research is spring soft wheat, Yoldyz variety.

The influence of the degree of climate continentality on the productivity of agricultural production

This article provides estimates of the influence of the degree of climate continentality on the yield of spring crops and on the quality of spring wheat grain. The analysis of variance was chosen as a research method, which makes it possible to assess the significance of the influence of one quantity on the variability of another. As a result of the study, it was found that the degree of climate continentality affects the formation of spring wheat yields ambiguously. For areas where there is an increase in the degree of climate continentality, there is a weak negative correlation between continentality and the yield of spring wheat. For grain-sowing areas, in which no increase in the degree of continentality was observed, there is a weak positive correlation between the yield of spring wheat and this characteristic. It was found that the increase in the degree of continentality reduces the yield, but improves the quality of the grain. Correlation dependencies are estimated at -0.25 and 0.62, respectively. It is shown that the degree of climate continentality determines the quality of grain. The contribution of the degree of continentality to the formation of protein content in spring wheat is estimated at 48%.

The tendency for the change of yield and grain quality of spring wheat (soft and durum) in the conditions of Oren-burg Cis-Urals

Grain quality is an indicator for the intensification of grain production, integrating the interaction of various agrotechnical measures and weather conditions. The purpose of this experiment is to determine the main trends in the yield and grain quality of spring durum and soft wheat in the conditions of the Orenburg Cis-Urals. The experiment was carried out in 2016-2020 at the permanent study area of the Department of Agriculture and Resource-Saving Technologies of the Federal State Budgetary Research Institution FRC BST RAS. The coordinates of the location of the test site is 55.306547º E 51.775125º N. The study established the influence of predecessors on the quality of wheat grain. The best among them were black fallow, winter crops, maize and peas. The quality of wheat grain cultivated in permanent crops without the use of mineral fertilizers decreased. The use of green green manure as fertilizer increases the content of wet gluten up to 34.0%. The aftereffect of green manure in severe dry years leads to an increase in the content of wet gluten in the grain of spring wheat.

The article presents the results of studies of the influence of soil cultivation methods, mineral fertilizers and biofungicide on yield, grain quality of spring wheat and economic indicators. The studies were carried out in 2018-2020. The soil of the experimental site is represented by slightly leached heavy loamy chernozem with a humus content of 5.8%. The object of research is spring wheat, grade “Ulyanovskaya 100”. The subject of research is six methods of soil cultivation: 1) moldboard - (plowing by 20-22 cm PLN-4-35) control; 2) differentiated - (plowing 25-27 cm for the previous crop, disking 6-8 cm for spring wheat); 3) mulching - (by 10-12 cm APK-3 in spring); 4) comb - (OP-3S for 13-15cm); 5) disk - (paper machine for 6-8cm); 6) flat-carved - (KPSh-3 by 13-15cm). The experiment was carried out on four backgrounds: 1) N0P0K0 (control); 2. Background (N30P30K30 - for pre-sowing cultivation); 3. “Fitotrix”; 4.Background N30P30K30 + Fitotrix. The experiment was repeated four times. The arrangement of the plots is systematic, the total area of the plot is 250 m2 (10 x 25), the accounting area is 125 m2 (5 x 25). The highest yield - 3.73 t/ha, was achieved with the use of differentiated tillage, here the profitability of grain production was 161%, the energy efficiency coefficient was 3.51 units, against plowing, where the indicators were respectively by 0.15 t/ha, 52% and 0.43 units below. The greatest responsiveness in the harvesting of grain from fertilizers was observed in the variant with ridge cultivation, where the increments were 0.49 t/ha against the background of the application of N30P30K30, against the background of N30P30K30 + “Fitotrix” - by 0.96 t/ha relative to the non-fertilized background. The quality characteristics of the grain were similar regardless of the main tillage methods. The highest indicators were observed in the combination of biofungicide with mineral fertilizers, where the increase in gluten and protein was 3.4 and 1.1%, compared with the non-fertilized background

Preservation of Soil Fertility Using Sidereal Clover

This study examined the use of intermediate groundcover sideral crops, such as perennial leguminous herbs, to conserve soil fertility though enriching the soil with fresh organic matter, an effective and low-cost method. Studies show that the use of direct sowing technology allows the preservation of all plant residues on the soil surface, which ensures the best accumulation of snow in the winter. Through the preservation of numerous biodrenes from the root system of sweet clover and other cultivated crops, as well as soil channels from earthworms, this direct sowing technology increases the moisture content of the soil and reduces moisture loss. The effectiveness of various soybean, corn and sunflower cultivation technologies with a minimal tillage period was studied. When sweet clover was used for green manure in April, the maximum yield was obtained, and the maximum yield for corn (57.3-82.3 c/ha) was obtained using the no-till technology. As a consequence, the ground cover crop had a noticeable effect on the yield of the second crop rotation - spring wheat, which had a higher yield. The use of direct sowing technology with sweet clover as green manure provided the highest yield of spring wheat - from 37.2 to 39.8 c / ha. The grain quality of spring wheat, placed as the second crop after melilot on green manure, was higher, both under no-till technology and under mini-till technology.

The Impact of Harvesting Time on Fusarium Mycotoxins in Spring Wheat Grain and Their Interaction with Grain Quality

In this work, we studied the impact of harvesting time on Fusarium mycotoxin occurrence in spring wheat and the effect of mycotoxin contamination on the quality of these grains. The spring wheat grains (Triticum aestivum L.) were collected in 2016–2018 when the crop had reached full maturity, 10 ± 2 days and 17 ± 3 days after full maturity. The grain samples were analyzed for Fusarium infection and co-contamination with mycotoxins deoxynivalenol (DON), zearalenone (ZEA), and T-2 toxin (T-2), as well as the quality of the wheat grains (mass per hectolitre, contents of protein, starch, ash and fat, particle size index (PSI), falling number, sedimentation, wet gluten content, and gluten index). The occurrence of Fusarium spp. fungi and the mycotoxins produced by them in the grains was mostly influenced by the harvesting time and meteorological conditions. The correlations between Fusarium species and the mycotoxins produced by them in the grains of spring wheat showed F. graminearum to be a dominant species, and as a result, higher concentrations of DON and ZEA were determined. The co-occurrence of all the three mycotoxins analyzed (deoxynivalenol, zearalenone, and T-2 toxin) was identified in wheat. In rainy years, a delay in harvesting resulted in diminished grain quality of spring wheat, as indicated by grain mass per hectolitre and falling number. Negative correlations were found in highly contaminated grains between mycotoxins (DON, ZEA, and T-2) and falling number and grain mass per hectolitre values.

Soil water regime, yield and grain quality of spring wheat using the direct sowing technology in the steppe zone of Altai Krai

The paper presents data on the influence of the direct sowing technology on the soil water regime, the yield and the grain quality of the spring wheat in the steppe zone of Altai Krai. The results showed that 2009 was the best year for the spring wheat yield; 2012, 2014 and 2015 were characterized by the minimum values of the soil moisture content and the spring wheat yield. However, there was the highest amount of gluten in grains during these years. The correlation between the yield and the water accumulation in the meter soil layer for the autumn-spring period was the highest, R=0.83. This can be taken into account in the direct sowing technology implementation in the spring soft wheat production.

The article presents the results of studies on the evaluation of legume precursors (soybeans, peas, lupin, chickpeas), methods of primary tillage, and plant protection during spring wheat cultivation in the conditions of chernozem soils of the Middle Volga region. Studies have shown that the studied precursors had different growing season duration and water consumption, which provided different water regimes and accumulation of productive moisture in the soil and ultimately affected the productivity of spring wheat. The accumulation of productive moisture in the soil occurs mainly in the autumn, winter, and spring periods; after harvesting peas, no more than 19% of precipitation (28–33 mm) accumulated after harvesting soybeans,lupine, and chickpeas – 29–39% (29–39 mm) until the time of a steady transition of air temperature below 5оC. According to the yield level of spring wheat, the researchers arranged the studied precursors in the following row: after peas – 3,80 t/ha > after chickpeas and lupine – 3,49–3,50 t/ha > after soybeans – 3,45 t/ha. There was an increase in the yield of spring wheat for combined tillage in crop rotation (for the studied crop – soil disking by 10–12 cm + plowing by 20–22 cm) in comparison with minimal tillage by 0,52 t/ha or by 15,6%, and on adaptiveintegrated plant protection by 0,36 t/ha or 10,6% in comparison with the level of standard technologies.The effect of the studied factors on the formation of yield was as follows: tillage – 40,7% > plant protection – 25,3% > precursors – 19,1%. The mentioned variants also increased the quality of spring wheat grain.

Effect of biohumus and growth regulators on the content of pigments and catalase, spike productivity and grain quality of spring wheat

The article is devoted to studying the influence of various treatment options for spring wheat seeds with biohumus and growth regulators. The results of field experiments led to the establishment of the effect of various seed treatment options on the content of chlorophyll, carotenoids and antioxidant enzymes, spike productivity indicators, grain quality indicators (nature, vitreous, raw gluten content). A positive effect of the studied preparations on the increase in the content of photosynthetic pigments, catalase, as well as the number of grains in an ear and the weight of grain per ear was established.

The Influence of the Preparation Megamix-Zinc on Yield and Grain Quality of Spring Wheat

The conducted study has shown a stimulating effect of foliar dressing of spring wheat plants with the preparation Megamix-zinc. It has been ascertained that it has a positive effect on such indicators as productivity and quality of spring wheat grain. The use of macro and microelement-containing preparations in modern technologies of spring wheat cultivation has a positive influence on such indicators as yield, protein content in grain, quantity and quality of gluten, mass fraction of starch in grain.

Influence of technology elements on the yield and grain quality of spring wheat in the northern forest-steppe of the Tyumen region

It was found that varieties Novosibirskaya 31 and Iren have an advantage in yield and grain quality over Omskaya 36 and Tyumenskaya 25 in terms of the predecessors of annual grasses and green manure fallow. For varieties Omskaya 36, Tyumenskaya 25, Iren, the background of mineral nutrition is optimal for obtaining a yield of 4 t/ha. A further increase in yield leads to a decrease in grain quality. The exception was the Novosibirskaya 31 variety, which retained the grain quality to a yield level close to 5 t/ha. The best sowing dates are the first and second.

Use of an environmentally oriented organic mineral fertilizer from liquid waste of pig farms in the cultivation of wheat

The article presents the results of a field vegetation experiment in the Rostov region on the cultivation of spring wheat of the “Zlata” variety with the use of an environmentally oriented organic mineral fertilizer from liquid waste of pig farms by the method of split plots with a randomized placement of variants in repetitions, the repetition of the experiment is three-fold. The agrochemical indicators of the soil before and after wheat cultivation at the horizons of 0-20 and 20-40 cm are given. The scheme of carrying out the experiment, including different doses of organic mineral fertilizer application and a plan for cutting plots, is indicated. During the growing season, constant observations of the plants were carried out together with the care. The dynamics of the growth of wheat biomass in different periods of time from planting and its yield are presented. The influence of different doses of ecologically oriented organic mineral fertilizer from pig manure on the yield of spring wheat is estimated. According to the results of experimental data, the effective dose of organic mineral fertilizer application from pig manure was established-2t/ha. The yield of grain crops (wheat) per hectare was determined-49.2 c / ha. The spring wheat variety “Zlata”, which is unusual for the Rostov region, gave a high yield when applying an environmentally oriented fertilizer, which proves its value both in agronomic and ecological terms. The absence of toxic effects on the soil of organic mineral fertilizers for heavy metals (copper, nickel. cadmium, lead), an increase in humus from 5.43% to 5.52%. The assessment of the nutrient reserves in seeds and the effect of organic mineral fertilizer doses on the quality of spring wheat grain of the «Zlata» variety is given. The highest amount of gluten-40.03% - was observed when using the fertilizer at a dose of 2 t / ha.

Agrotechnological assessment of the application of biological preparations and micronutrient fertilizers in spring wheat

The results of the research on the assessment of the effectiveness of the application of biological fertilizer Humistim and micronutrient fertilizers MicroFeed Complex and MicroFeed Extra Phosphorus in the cultivation of spring wheat under the conditions of Kursk Region are presented. As a result of the research, it was found that the preparations (Humistim, MicroFeed Complex and MicroFeed Extra Phosphorus) contributed to the better growth and development of spring wheat, reduced the development of leaf-stem diseases, increased the yield and quality of spring wheat grain. Thus, when treating seeds (5 l/t) and crops in the tillering phase and early booting (5 l/ha) with Humistim fertilizer, the development of septoria was 16.4 %, biological efficiency was 36.4 %, the yield of spring wheat increased by 0.55 t/ha, gluten content in the grain by 2.1%, compared with the control variant. When using micronutrient fertilizers MicroFeed Complex and MicroFeed Extra Phosphorus at a rate of 1.5 l/t for seed treatment and 1.5 l/ha for crop treatment in the tillering phase and early booting the biological efficiency was slightly lower and amounted to -32.6-33.7 %, the yield of spring wheat increased by 0.52-0.53 t/ha, the gluten content in the grain by 1.7-1.9 %. Calculations of economic efficiency showed that the treatment of seeds and crops of spring wheat with the biological fertilizer Humistim increased direct production costs by 825 rubl./ha, but due to the increase in yield, the cost of gross production increased by 6,600 rubl./ha, conditional net income by 5,775 rubl./ha, the cost of 1 ton of grain decreased by 511.55 rubles. The efficiency of using fertilizers with micronutrients MicroFeed Complex and MicroFeed Extra Phosphorus with similar methods of application was slightly lower: the value of conditional net income was 27,693.31-30,255.31 rubl./ha. MicroFeed Extra Phosphorus fertilizer provided a minimum increase in conditional net income 2,940 rubles/ha, which is due to its higher cost.
